Method, apparatus, and system for disaster recovery of IMS
First Claim
1. A method for disaster recovery, comprising:
- sending, by a network storage entity, information of registered Internet Protocol (IP) Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with an IMS Public User Identity (IMPU) in an IMS subscription to a Call Session Control Function (CSCF);
obtaining, by the CSCF, the information of registered IMPIs that are associated with the IMPU;
requesting, by the CSCF, user service configuration data of the IMPU and user backup data of IMPIs associated with the IMPU from the network storage entity when at least one IMPI received from the network storage entity is not registered in the CSCF;
receiving, by the network storage entity, a request for the user service configuration data of the IMPU and the user backup data of IMPIs associated with the IMPU from the S-CSCF;
sending, by the network storage entity, the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU to the CSCF; and
receiving, by the CSCF, the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU in a response from the network storage entity, wherein the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU is used by the CSCF for recovering a corresponding service.

Abstract
A method, apparatus, and system for disaster recovery of an Internet Protocol (IP) Multimedia Subsystem (IMS), where the method includes triggering a redundant Call Session Control Function (CSCF), obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. Hence, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.

8. An apparatus for disaster recovery, comprising:
-
a receiver configured to receive information of registered Internet Protocol (IP) Multimedia Subsystem (IMS) Private User Identities (IMPIs) that are associated with an IMS Public User Identity (IMPU) in an IMS subscription from a network storage entity; and a processor coupled to the receiver and configured to; obtain the information of registered IMPIs that are associated with the IMPU; and request user service configuration data of the IMPU and user backup data of IMPIs associated with the IMPU from the network storage entity when at least one IMPI received from the network storage entity is not registered in a Call Session Control Function (CSCF), wherein the receiver is further configured to receive the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU from the network storage entity, and wherein the user service configuration data of the IMPU and the user backup data of the IMPIs associated with the IMPU is used by the CSCF for recovering a corresponding service. - View Dependent Claims (9, 10, 11, 12, 13, 14)
